Hi,
I'm trying to set an environment variable in httpd.conf and then have
it available to the URL-portion of a RewriteRule in a .htaccess file.
Please could someone assist:
In httpd.conf I have this line setting the environment variable:
SetEnv MODPERLPORT 81
and in .htaccess I want to do something like this:
RewriteEngine On
RewriteRule foo\.cgi
http://myserver:%{ENV:MODPERLPORT}%{REQUEST_URI} [P,L]
to have Apache proxy the request through to another Apache process
running on a different port, but it doesn't seem like any environment
variables are available in the URL portion of the rule.
I've also tried to do things like this:
RewriteEngine On
RewriteCond %{ENV:MODPERLPORT} ([0-9]+)
RewriteRule foo\.cgi
http://myserver:%1%{REQUEST_URI} [P,L]
but the condition fails, even though the environment variable is set
if I look at a simple dump of the environment e.g. env.cgi through a
browser.
So far the only hacky way I can get this to work is to set a built-in
variable to the value I need, e.g.:
httpd.conf:
ServerAdmin 81
.htaccess
RewriteEngine On
RewriteRule foo\.cgi
http://myserver:%{SERVER_ADMIN}%{REQUEST_URI} [P,L]
but that's clearly a very poor solution for many reasons, not least
that I need the modperlport to vary for different environments without
the .htaccess file having to change for each environment.
Can anyone advise if there's a better/correct way to set customised
environment variables and then de-reference them within the URL
portion of a rewrite rule?
Thanks.
